I have an Orange Rocker 30 and I think the valves may need replacing. Anyone know how much this will cost me? To get them replaced and to buy them i mean

around 30 bucks

At the very minimum. (like the cheapest tubes you could buy)
It cost me about 40-60 (can't remember) to get a matched pair of 6L6's and have them biased in my Fireball. Then I spent about 80 on 4 new preamp tubes, but they were extremely high quality.
